The -enablesystemassertions option supplies a separate switch to empower assertions in all program courses.
Each and every line during the command file signifies a command, a class name, and a technique title for which the command is utilised. As an example, this line prints assembly code for the toString() way of the String course:

Specifies the most size (in bytes) of disk knowledge to maintain for that default recording. Append k or K, to specify the scale in KB, m or M to specify the size in MB, or g or G to specify the dimensions in GB. By default, the most size of disk facts isn’t limited, and this parameter is about to 0.
Instructs not to print the compile instructions. By default, the commands that you choose to specify While using the -XX:CompileCommand option are printed; by way of example, when you exclude from compilation the indexOf() way of the String course, then the subsequent is printed to straightforward output:
Permits tracing of all loaded lessons within the order during which they’re referenced. By default, this option is more info here disabled and lessons aren’t traced.
